Compressor



resurgence-14. i926.

This invention relates yto oil Wells and has for an object the provisionofa cheap, novel l and cieient inethod for forcing Vwater and.

air (either together` or separately) through thc and rock for the purpose of forcing oil into other wells.

Heretofore it has been customaryto till the well tubing with water and to depend upon the pressure of the column of water lll thus formed, to force the oil throughthe sand= -or to "force air under' pressure into the tubing by means of compressors; The

li'rst n'zethod isexccedingly slow, while the` second Vmethod is expensive as the compressors must bev kept in constant, operation.

y vThe method which constitutes the present. invention utilizes both air and Water in suoli i a way that. a constant. and suilicient pres- 4 sure is provided which will readily' force the oil'th-rough the sand rock, while the ex` lpense of the and pointed out in the operation is reduced to a inin-r imnmrV lVith the abore and other objects in View",A v the invention further includes the follow- Aing novel features and details of construcsection.

Referring to the drawings in detail wherein like characters of reference denote cor- 'responding parts, the reference character 10 indicates the casing of an oil Well within which extends the tubing 11..

The invention comprises a cylinder 12 which is providedv at its lower end with a head 13, while extendingfrom the latter is a reduced tubular portion 14 connected to the tubing 11 by a union 15. Thustlie cylinder 12 is-in communication with the Vtubing t The cylinder 121 as shown is vertically arranged and is provided with a piston 16, the

latter being preferably equipped with the usual packing rings.. Extending from ithe applicaties ined Januari 2, 1925. serial na. v215i.
